Infer alignment of loads and increase their alignment when we can tell they are
from the stack. This allows us to compile stack-align.ll to:
_test:
movsd LCPI1_0, %xmm0
movapd %xmm0, %xmm1
*** andpd 4(%esp), %xmm1
andpd _G, %xmm0
addsd %xmm1, %xmm0
movl 20(%esp), %eax
movsd %xmm0, (%eax)
ret
instead of:
_test:
movsd LCPI1_0, %xmm0
** movsd 4(%esp), %xmm1
** andpd %xmm0, %xmm1
andpd _G, %xmm0
addsd %xmm1, %xmm0
movl 20(%esp), %eax
movsd %xmm0, (%eax)
